Short description Identification keys | Morphology | Morphometrics

Differs from other species in the genus by many dorsal-fin rays, 21-25 versus 1220 and anal fin origin under dorsal-fin ray number 13-16 compared to 4-11. Dorsal fin origin anterior to origin of pelvic fin; posterior to pelvic fin origin in other species (Ref. 26761).

In rivers. Females bear live young (Ref. 58777).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.4 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
